The issue is related to `Tracking Protection` breakage.

Looking at the devtools console, here are the blocked resources:
The resource at “https://media.richrelevance.com/rrserver/js/1.2/p13n.js” was blocked because content blocking is enabled.
The resource at “https://www.google-analytics.com/analytics.js” was blocked because content blocking is enabled.
The resource at “https://www.googletagmanager.com/gtm.js?id=GTM-PPKPK5” was blocked because content blocking is enabled.

So below are the domains to test:
- media.richrelevance.com
- www.google-analytics.com
- www.googletagmanager.com

I opened the URL in a fresh browser profile (Firefox Nightly 66, uMatrix installed, normal mode) and loaded the page. The products are not displayed.

I disabled the Spoof Referrer option in uMatrix and then WHITELISTED:
- aldi-digital.co.uk (including all related domains)
- richrelevance.com (including all related domains)
and the products are displayed.

The other resources didn't help. 

So in conclusion:
- richrelevance.com is in Advertising category = [tp-ads]

The reduced section is working for me in strict mode now.
